The buttons (EKA 162 only)
When you want to change a setting, the
two buttons will give you a higher or lower
value depending on the button you are
pushing. But before you change the value,
you must have access to the menu. You
obtain this by pushing the upper button
for a couple of seconds - you will then en-
ter the column with parameter codes. Find
the parameter code you want to change
and push the two buttons simultaneously.
When you have changed the value, save
the new value by once more pushing the
two buttons simultaneously.
